Application filed June 1, 1914. Serial No. 842,286.

To (/7Z 11 7107712 m up concern Be it known that I, ARTHUR M. ROLAND, acitizen of the United States, residing at San Francisco, in the countyof San Francisco, State of California, have invented a new and usefulDispensing Device, of which the following is a specification in suchfull and clear terms as will enable those skilled in the art toconstruct and use the same.

This invention relates to a portable tank for gasolene or oil and itsobject is to produce a portable tank which will have a suitableapparatus connected therewith discharge the gasolene or oil from thesame in measured quantities withoutattention upon the part of theoperator when once the apparatus has been started.

It will be understood by those skilled in the art that around garagesand automobile supply stations, there is usually a plentiful supply ofcompressed air so that it is usually possible to operate any desiredmachinery in that way. In this instance a tank to be charged isconnected to the gasolene tank and carried around therewith to operatethe gasolene pump, said pump discharging gasolene so long as there is asupply of compressed air in the air tank.

Another object of the invention is to provide a device for automaticallydischarging a number of desired different amounts of the liquid. If itis desired to discharge the liquid a quart at a time, it may be done, orif a gallon at a time is desired, that amount may be discharged.

In the drawings. in which the same reference numeral is applied to thesame portions throughout, Figure l'is a vertical elevation of thecompleted apparatus, a portion of the tank being shown in verticalsection for purposes of illustration. Fig. 2 is a plan view of thecompleted apparatus. Fig. 3 is a vertical sectional view of thecompleted apparatus on the line 33 of Fig. 1. Fig. 4 is a plan view ofthe pump cylinder. Fig. 5 is a view of the end of the pump cylindershowing its position with respect to the bottom of the gasolene tank.Fig. 6 is a vertical sectional view throughthe engine cylinder. Fig. 7is a front elevation of the engine cylinder and valve-box. Fig. 8 is ahorizontal sectional view of the engine cylinder. Fig. 9 is a sideelevation of the pump lever operating apparatus and Fig. 10 is a planview of the pump lever link.

The numeral 1 is applied to the gasolene receptacle, which in thisinstance is a rectangular tank of any desired size, said tank beingsupported on wheels 2 and 3, which with the trunnions l and 5 connectedto the tank, form a carriage.

At the front end of the tank there is a suitable bracket 6, andcaster-wheel 7, carried by a revolving standard 8, extending into thebracket 6. On each end of the tank there is a bail, as indicated at 9and 10, for the use of the operator in pulling the tank around fromplace to place. On the bottom of the tank there are two metal bands 11and 12. Said bands support an air-tank 13 for the storage of thecompressed air necessaryto operate the apparatus. The air tank 13 isprovided with a discharge pipe 14, having a suitable. connection 15 forsupplying the tank with compressed air when the air contained thereinhas been dis charged. The pipe 14 has a valve 16 for the regulation ofthe air when the gasolene is to be discharged from the apparatus, a pipe17 extending from said valve to the valve-box 18 on the side of theengine cylinder 19. At the side of the air cylinder below the tank thereis a pump cylinder 20. This pump cylinder is closed by means of a plug:21, at one end, and a plug 22 at the other end, the latter plug havinga pipe 80 connected therewth for the discharge of the gasolenetherethrough. and also having a chamber 24 therein which has an openingin register, with an opening in the top of the pump cylinder 20. At theback of the chamber 24', there is an opening leading into the pumpcylinder, which opening is covered by means of the valve 25, said valvebeing suitably weighted to remain closed normally, although it is freeto open upon the return stroke of the pump piston. In order to provide adefinite stop for the pump piston 26, a flange 27 is formed within thepump cylinder. At the end of the pump cylinder adjacent to plug 21,there is a long slot 28, said cylinder having suitable flanges 29 and 30for connecting it to the bottom of the gasolene tank, asuitable gasket31 being interposed between said cylinder and the pump cylinder toprevent leakage. It will also be observed that there is a bolt 32adjacent to the stop 27 for con.- necting the pump cylinder and tankbottom in order to insure a tight joint with the opening 33 in thebottom of the tank.

The piston 26 has a link 3i connected therewith for operating same.which link is connected to a long lever 35, mounted upon the trunnion36, bolted to the side of the casing at 37. At the upper end of thelever there is a short link 38 pivotally connected therewith. The link38 has two brackets 39 and 4-0 bolted thereto, which brackets carry arod ii, on which rod two spiral springs 4:2 and 4-3 are placed. Thesetwo spiral springs contact with a lever 4'4 and permit a certainmovement thereof. necessary to the operation of the apparatus. as willbe later explained. At the end of the link 38 there is a hook 45, whichbook is connected with a spiral spring 46, said spring being connectedat its opposite end to a ring 47 in the opposite end of the tank 1. Thelever H is carried by a shaft 50, extending vertically through a bearing51 bolted to the top of the gasolene tank. This shaft 50 carries on itsupper end a similarly placed lever to the lever 4i, the former beingconnected with the piston rod 53, said piston rod being pivotallysupported at its opposite end in lugs formed on piston 54. said pistonbeing movable in the cylinder 19. At the side of the back end of thecylinder 19 there is a valve-box 18, within which there is installedoscillating valve This valve has ports 56, 57 and 58 and is sopositioned that when the valve operating rod 59 is reciprocated, that itwill be operated by means of the short arm 60, connected therewith, toshift it from the inlet position as indicated in Fig. 8, to such aposition as will permit the port 58 to register with the exhaust port(32 in the valve-casing 18. The valve operating rod 59 is carried inslides 63 and (H on the side of the cylinder 18 and it has an extension65 which is provided with an upward extending arm (36 for the operationthereof. The piston rod 53 is provided with a. depending bracket 67,which upon the return stroke of the pump contacts with the arm 66 andreturns the valve in the casing 18 to the inlet position, while tomeasure any particular quantity of gasolene, the stop arm 68 pivotallyconnected with the piston at 69, is moved from one position to anotherso that either of the stops 7071 or 72 may contact with the arm 66, andsince the arms ()5 and 66 are made strong enough to stop the apparatuseven when under pressure. they will not only cause the reversal ofmovement of the piston by the releasing of the air in the cylinder 19,but will act as means for absolutely determining the precise quantity offluid to be discharged from the pump. The rod 59 is provided with a stop73 in order to precisely determine the point at which the piston will befinally stopped. In order to adjust the arm 68, a spring 74 bears uponthe same and tends to hold it down, while it is provided with anupwardly extending arm 75 and with a lateral extension 76, which lateralextension is provided with a plurality of notches 77, as indicated inFig. 7, thus enabling the operator to shift the stop as he may desire todischarge more or less gasolene at each stroke.

In order to fill the tank a cap 76 in the top thereof is provided. Theoperation of the apparatus is as follows, it being assumed that the tankis filled or partially filled with gasolene: The air tank is chargedwith air at a suitable pressure. The normal position of the apparatus isindicated in Fig. 3. in which the spring 46 has caused the pump pistonto fill the pump cylinder with gasolene. After being so filled withgasolene the operator opens the valve 16, whereupon air will pass intothe engine cylinder (not-c Fig. 8) and will force the piston thereinoutwardly. until one of the stops or the piston itself contacts with thevalve operating rod,

whereupon the valve will be turned to the exhaust position and thegasolene will have been delivered through the discharge pipe 80,connected with the pump. whereupon the pump piston will be returned tothe posi tion shown in Fig. 3, by the spring 46. said spring being onlyheavy enough to insure' the return of the apparatus to the initialposition ready for another discharge. It will be apparent that so longas valve 16 re mains open that gasolene will be discharged from theapparatus in definite volumes intermittently, the valve allowing thegasolene to run from the tank into the pump cylinder and preventing itsreturn to the tank.

The pipe 80 is provided with a hose connection 81 and faucet 82, such asis commonly used in the art. The object of the springs 4243 is to. allowa slight movement of the position of the pump pistons and engine pistonswith respect to each other. to insure against injury to one part or theother.

In order to enable the purchaser to know that he is getting the amountof gasolene he has asked for a suitable registering or indicating meterM is installed in the pipe 89 at the top of the tank.

It is to be especially noted that the gasolene tank is practically airtight, save for the opening necessary to permit the removal of thegasolene therefrom, and that the air used for the operation of the pumpcannot at any time get into the gasolene tank.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States, is as follows,modifications within the scope of the claims being expressly reserved.
